Which of the following processes for refining of metals involves a principle of selective adsorption of the components from a mixture.
Electrolytic refining
Chromatography
polling
Zone refining
Solution
Correct answer is chromatography.
Adsorption chromatography uses a stationary phases in the solid state and mobile phase in liquid or gas state. It works because there's a balance that each solute has between adsorption on the surface of the solid and solubility in the solvent.
